Patent EP-0320058-A2 (EP)
Inventor: SHARPE ROBIN
IPC: H04L27/22
Filed: 1988-12-05
Abstract: An arrangement for producing a phase error signal representing the phase error between a received phase-modulated signal and a locally generated carrier signal. The arrangement comprises two exclusive-OR gates (4) and (5) to which the received signal q(t) and sine and cosine versions s(t) and c(t) of the carrier signal are applied. The outputs of the two gates (4) and (5) control according to their level (high or low), the up/down counts of respective up/down counters (6) and (7). These counts are latched periodically by latches (9) and (10) and the latched values are modified in 2's complementers (11) and (12) and then summed in a binary adder (13) to produce a resultant phase error signal (z).

Abstract: A container closure designed as a screw closure 7 with an annular tamper prevention element 11 adjoining the screw closure via thin lugs 10 designed as predetermined breaking points, which element 11, on screwing on, is capable of going beyond a conical flank of an annular projection surrounding the filling neck, which has the screw thread, of the container, and which, on unscrewing, is blocked by its opposite steep flank, is to be developed in such a manner that the destruction of the lugs 10 can be brought about when the container is opened without the inconvenient tendency of the tamper prevention element at least at some points to climb over the annular projection.   To this end, the cylindrical region of the filling neck below its annular projection is equipped with advantageously at least two wedge-shaped protuberances, and the tamper prevention element 11 is provided with noses 12, which are wedge-shaped in the opposite direction, in such a manner that the protuberances of the filling neck and the noses of the tamper prevention element form a locking mechanism which, although it allows the screwing on of the screw closure 7, locks the security ring upon unscrewing, however, so that the lugs 10 can be sheared off by the torque applied upon unscrewing.   <IMAGE>

Abstract: A method is disclosed for managing marker entities within a document data stream independently of the content of the data stream. The method provides consistent specification and independent processing of marker entities which may include both text and non-text data and which may be associated physically and/or logically with data stream content at the document or lower order entity level. A define marker structure control is utilized within the data stream to specify in a data type independent fashion the physical structure and content of a marker entity as well as defining any desired relationship of a marker entity with another entity within the data stream. A map marker control is then utilized to control the position within a presentation area where the marker entity is to be imaged. In this manner, the method of the present invention provides a flexible, efficient and useful manner to associate a marker entity within a document data stream which may be tied to specific layout areas during presentation and which may be easily manipulated at a data stream level.
